I feel I have to share with everyone the ostomy bag and glue that finally worked well for my husband. It is called Marlen Deep Convexity Pouch with the Skin Shield Barrier. Use Nu-Hope glue with it.
Before we tried it he couldn't keep a bag on for 24 hours without a leak. Please try it if you are having problems and be sure to use the glue with it as I don't think it will stick properly without the glue. The trick to the glue is to apply it to the wafer and let it dry for about 4 minutes before applying it to the skin. Really hope this helps someone. It made a huge difference in our lives.
